Wangari Maathai in the Los Angeles Times:
African leaders have much to learn from the new president’s example. His campaign was disciplined, inclusive and grass-roots-led. He has built his Cabinet methodically, reaching out to political opponents. And when he has made mistakes, notably in vetting some candidates for Cabinet positions, his apology and acceptance of responsibility stood in sharp contrast with the arrogance and lack of transparency that too often have marked 50 years of post-independence African leadership.
